2" 0 all whom it may concern:

Be it known that 1, LEE H. PARK, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in a Foldable Egg Case; andI do hereby declare the following to be a full, clear, andexact-description of the invention, such as will enable others skilledin the art to which itappertains to make use the same. 1 I

The object of the invention is to provide a simple, inexpensive andefiicient foldable or collapsible egg case adapted for use in theshipment of transportation of eggs with security to the contents andcapable of being folded into compact form for returnto the dealer orproducer so asto minimize space and therefore cost of returntransportation; and more especially to provide a device of the typeindicated wherein the security of the contents of the receptacle againstsurreptitious removal or substitution may be insured; and with theseobjects in view the invention consists in a construction, combi nationand relation of parts of which a pre ferred embodiment is shown in thedrawings, wherein:

Figure 1 is a perspective view of a case embodying the invention incondition for shipment or transportation, the same being partly brokenaway to indicate the collapsible fillers or cells.

Figure 2 is a similar view showing the top and bottom lids in openposition.

Figure 3 is a view showing the crate collapsed or folded.

Figure at is a detail enlarged sectional view of one of the clasps bywhich the free edges of the lids or covers are secured in closedposition.

Figure 5 is an enlarged detail perspective view of one of the fasteningdevices with the elements of the clasps engaged and sealed.

Figures 6 and are detail views respectively of the members of the claspsdetached.

Figure 8 is a fragmentary view of an end portion of the crate whenfolded,part of the end wall being broken away.

The case consists essentially of the side walls 10, the end walls 11,and the top and bottom lids or covers 12, an intermediate partition 13preferably being employed to connect the centers of the side walls, andsaid end walls and partition being hinged at their edges to the sidewall to permit of folding into compact flat form as shown in Figure 3,the hinges being indicated at 14.

The top and bottom lids are correspondingly hinged at 15 to the oppositeside walls at their remote edges and the hinges are preferably of thestrap form to provide transverse braces 16 to stiffen the lid. Thefillers or cells 17 are of the usual collapsible or foldable form whichmay readily be arranged between the side walls when the case is folded,and a retaining cord or tie 18 may be extended around the folded packageto hold the same in compact form as indicated in Figure 3.

The clasps by which the free edges of the lids are secured to the sidewalls consist re spectively of a tongue member 19 which is hinged as at20 to the extremity of one of the reinforcing straps 16 and is providedat its free end with a laterally reduced loop 21 offset inwardly fromthe plane of the body portion 22 of the tongue to form an abruptshoulder 23, while the keeper mem ber of the clasp consists of a plate24 having a beveled offset 25 provided with a longitudinal slot 26.Plate 14- is bowed forwardly at 27 for engagement with the shoulder 28of the tongue. The slot is bounded at its lower side by terminallyoverlapping fingers 28 and 29 springing from and formed as a part of theoffset portion 25 of the plate and adapted for engagement by the loop 21as shown in Figure 5, the engagement being effected by placing the loopagainst the finger 29 and pressing it rearwardly to cause the shoulder23 to pass under the bulge 27 and at the same time rearwardly spring thefree end of said finger 29 so that the fingers 28 and 29 will be inthreaded engagement with the loop 21. The loop thus engaged with theyielding terminally overlapping fingers and with the shoulder 23 engagedbeneath the bulge 27 to afford resistance to the opening or raisingmovement of the lid, a sealing wire 30 is engaged with the loop and witha perforation 31 on the base plate to prevent such lateral movement ofthe loop or the tongue which carries the loop as will permit ofdisengaging the loop from the fingers by a movement similar to thatrequired in the engagement thereof. In order to disengage the tongue topermit of the raising of the lid, therefore it is necessary to break theseal and move the loop which hasvsufiicient play about its pintle as at20 so as to cause the inner side thereof to pass between the overlappingextremities of the lingers and 29 and thereby remove the shoulder fromengagement with the bulge 2K.

ithe end walls are preferably extended to form reinforcing; lips 32 tooverlap and lie in contact with the end edges of the lid, the latterclosing between the same and thus stitfening the structure against anytendency to colla se or told.

Having thus described the invention, what I claim is V 1. A folding eggcase havin side and end walls hingedly connected attheir adjacent edges,top and bottom lids respectively hinged to remote edges of said sidewalls and terminally engageable with projecting edges of the end walls,and clasps for the tree edges of said. lids, consisting of inter lockingtongues and keepers respectively carried by said lids and side walls.each of said tongues being pivotally mounted and having a transverselyreduced terminal loop Yand an adjacent ottset or shoulder, and thecomplemental keeper having a bulge for engagement by said shoulder andterminally'ttree overlapping fingers tor threaded engagement with saidloops.

' 2. A folding case having side and end walls hingedly connected attheir adjacent edges, top and bottom lids respectively hinged to remoteedges of said side walls and terminally engageable with projecting edgesof the end walls, and clasps for the free edges of said lids, consistingof interlocking tongues and keepers respectively carried by said lidsand side walls, each of said tongues being pivotally mounted and havinga transversely reduced terminal loop and an adjacent offset or shoulderand the complemental keeper having a bulge for engagement by saidshoulder and terminally free overlapping fingers for threaded engagementwith said loops, the keeper being stretched from a single plate andhaving slot separating said bulge from the fingers, and having adjacentmeans for engagement with a seal. 7

3. A device of the class described having a tongue and a keeper tosecure a part in closed position. said keeper having overlappingfingers, and said fingers being adapted for threaded engagement withsaid tongue.

4-. A device of the class described having -a tongue and a keeper to'secure a part in LEE H. PARK.
